(Main)Specification for mortar for masonry - Part 2: Masonry mortar
Specification for mortar for masonry - Part 2: Masonry mortar
This European Standard specifies requirements for factory-made masonry mortars (bedding, jointing and pointing) for use in masonry walls, columns and partitions (e.g. facing and rendered masonry, load bearing or non-load bearing masonry structures for buildings and civil engineering works).
This European Standard defines for fresh mortar the performance related to workable life, chloride content, air content, density and correction time (for thin-layer mortar only). For hardened mortar it defines, e.g. performances related to compressive strength, bond strength, density measured according to the corresponding test methods contained in separate European Standards.
This European Standard provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard. The marking requirement for products covered by this European Standard is included.
This European Standard covers masonry mortars defined in Clause 3 with the exception of site made mortar. However, this European Standard or part of this European Standard may be used in conjunction with codes of application and national specifications covering site made mortar.
Festlegungen für Mörtel im Mauerwerksbau - Teil 2: Mauermörtel
Diese Europäische Norm legt die Anforderungen für Werkmauermörtel (für Untermauerungen, Fugenglattstrich und Verfugen) zur Verwendung in Wänden, Pfeilern und Trennwänden aus Mauerwerk (z. B. Verblendmauerwerk und verputztes Mauerwerk, tragende und nicht tragende Mauerwerkskonstruktionen für Hoch- und Tiefbauten) fest.
Für Frischmörtel beschreibt diese Europäische Norm die Leistungsanforderungen in Bezug auf Verarbeitbarkeitszeit, Chloridgehalt, Luftgehalt, Rohdichte und Korrigierbarkeitszeit (nur für Dünnbettmörtel). Für Festmörtel werden die Leistungsanforderungen z. B. in Bezug auf Druckfestigkeit, Verbundfestigkeit und Rohdichte definiert. Alle Eigenschaften werden nach den entsprechend festgelegten Prüfverfahren, die in gesonderten Europäischen Normen enthalten sind, ermittelt.
Diese Europäische Norm stellt ein Verfahren zur Bewertung und Überprüfung der Leistungsbeständigkeit (AVPC) der Produkte mit dieser Europäischen Norm zur Verfügung. Anforderungen an die Kennzeichnung der von dieser Europäischen Norm abgedeckten Produkte sind enthalten.
Diese Europäische Norm gilt für Mauermörtel nach Abschnitt 3 mit der Ausnahme von Baustellenmörtel. Diese Europäische Norm oder Teile davon dürfen jedoch im Zusammenhang mit Anwendungsvorschriften und nationalen Festlegungen auch für Baustellenmörtel angewendet werden.

Specifikacija za malte za zidanje - 2. del: Malta za zidanje
Ta evropski standard določa zahteve za tovarniško izdelane malte za zidanje (podlage, spoji in fugiranje) za uporabo na zidovih, stebrih in pregradah (npr. zidava fasad in oblaganje, nosilne ali nenosilne zidarske konstrukcije za visoke in nizke gradnje).
Ta evropski standard opredeljuje zmogljivost sveže malte v zvezi z obdelavnim časom, vsebnostjo kloridov, vsebnostjo zraka, gostoto in časom popravka (samo za tankoslojno malto). Za strjeno malto opredeljuje npr. zmogljivost v zvezi s tlačno trdnostjo, sprijemno trdnostjo, gostoto, izmerjeno v skladu z ustreznimi preskusnimi metodami, navedenimi v ločenih evropskih standardih.
Ta evropski standard omogoča ocenjevanje in preverjanje nespremenljivosti zmogljivosti (AVCP) proizvodov v skladu s tem evropskim standardom. Vključena je zahteva za označevanje proizvodov, ki jih zajema ta evropski standard.
Ta evropski standard zajema malte za zidanje, opredeljene v točki 3, z izjemo malt, pripravljenih na gradbišču. Vendar se lahko ta evropski standard ali njegov del uporablja v povezavi s pravilniki za uporabo in nacionalnimi specifikacijami, ki zajemajo malte, pripravljene na gradbišču.
